Age&Gender Covariates; Continuous data; Multivariate Analysis

I would like to covariate for age & gender in a multivariate analysis. I found scripts to covariate but in ordinal data and in univarite analysis.

It would be really helpful for me it any of you could show me an example of a script on how to covariate (by age and gender) in a MV analysis, because I now from my previous univariate analysis that gender could be causing some genetic sex differences in 4 of the 6 traits that I’m using.
